| 1. | □ | There are basically two different options to access the Internet today. |
| 2. | □ | The main problems with broadband access are that it is rather expensive and it doesn`t reach all areas. |
| 3. | □ | The main advantage of WiFi access is that hotspots are very large, so coverage is broad. |
| 4. | □ | WiMAX doesn`t provide the high speed, wireless access and broad coverage. |
| 5. | □ | WiMAX also goes by the IEEE name 802.16. |
| 6. | □ | WiMAX could replace cable and DSL services, providing universal Internet access. |
| 7. | □ | WiMAX operates similar to WiFi but at lower speeds, over small distances and for a smaller number of users. |
| 8. | □ | A WiMAX system consists of two parts: a WiMAX tower and a WiMAX receiver. |
| 9. | □ | A single WiMAX tower can provide coverage to a very large area ─ as big as 5, 000 square miles. |
| 10. | □ | Non-line-of-sight transmissions use higher frequencies, with ranges reaching a possible 66 GHz. |
| 11. | □ | The final step in the area network scale is the universal area network (UAN). |
| 12. | □ | A true GAN would work a lot like today`s cell phone networks, with users able to travel across the country and still have access to the network the whole time. |
